Unscientific quotes for the interventional cardiologists

A poorly deployed drug eluting stent is far inferior to a properly deployed bare metal stents

Doing a plain old balloon  angioplasty ( POBA)  is not a scientific crime , millions of coronary lesion just  need that! ( Click here -Why POBA is important ? )
PCI is most effective during an ACS than a chronic coronary syndrome
Primary PCI is a [...]

Ventriculophasic sinus arrhythmia in complete heart block

Ventriculophasic sinus arrhythmia is a non-respiratory sinus arrhythmia seen in complete AV block.
The PP interval enclosing a QRS complex is shorter than a PP interval not enclosing a QRS.
The Mechanism 

The proposed mechanism is the  increased blood flow into the SA node artery  during ventricular systole  stimulating it to produce an early pacemaker activity [...]

Many cancers are curable , While common cold is not !

The irony of medicine is unlimited !  100 years of active clinical  research   failed  to find a specific cure for the rhino virus mediated common cold.In fact  US Govt stopped funding for this .
While ,   complete cure is possible  for many of the cancers, especially hematological ones !
Message 
In medicine there are thousands  of [...]

What is the clinical significance of ramus intermedius coronary artery ?

                                                      Coronary arterial circulation is the life line for  the human heart  and it’s survival.Typically it is supplied by two coronary arteries,  left and right coronary artery.Both, together carry about  250ml of blood every minute.( Approxinately  equal to a  cup of  coke !  ).These coronary arteries  generally divide in a predetermined  fashion , and have multiple [...]

Why should a stent elute drug ?

Stents are mechanical  devices like  a  spring ,  used to  keep an artery open after a PTCA or PCI.

                                Bare metal stents(BMS) were found to have restenois rate of about 25%.  So it was perceived a stent should have it’s own protective coat , so that it won’t get restenosed.For this the researchers thought  anti cancer [...]

Drug eluting stents bare it all ! and bare metal stents cover it all !

                                      One of the important principles of  post PCI care is,   we need  to be very careful  till the metal struts are fully endothelialised . This is of vital importance as improper endothelialisation  is a powerful trigger and nidus for a  imminent thrombosis and  acute coronary syndrome.

It is a billion dollor irony , the [...]

Management issues in systemic hypertension : Too many choices and too many guidelines !

Let us not forget the basics !

HT management has been made  easier with the availability of  many  good drugs , at the same time it has become a complex  issue with as many classification and guidelines.
The management of HT has evolved over the decades. Now we have realised  HT  is not a simple number game . [...]

What is sinus pause ?

 
Sinus node  as the pacemaker , orchestrates the rhythm of life . It has  to fire for the entire life time of  a person.It  can not afford to take any rest ! But it can pause a little bit , of course that pause  could  be less  than 15% of it’s basic sinus length. This variation of sinus  [...]

What is the purpose of declaration of conflict of interest in medical research ?

                                                 It is now mandatory for all  journals  to declare the  conflict  of interest by the authors  who are involved in medical research .The purpose apparently is to make all transactions or links  between the researchers and their funding agencies transparent .Even major journals  do not go beyond this . Some ensure it , to appear in the first [...]
